I'm puzzled about what you mean by liners in a Cadet. Here's a pic of a recent one. There is a very low divider in the center which is not that easy to see in the pic. Is that what you mean by liner? The alox itself is the outer liner.
OK, time to feel relief & admit embarrassment! I've had a look at the liner under cooler light & am pleased to report it does appear to be nickel silver. I can see the faint brass colour of the metal. The other day it looked more silvery next to the liners on my other alox knives.It makes me wonder if reports of Vic changing the liner metal to aluminium are mistaken. The OP in the thread below believed his new PX had Al liners. They do look different to two other older knives next to it, but perhaps the appearance turned out to be a trick of the light there, too.https://forum.multitool.org/index.php?topic=83818.0
